Conflux got extremely imbalanced units. Sprite is a good shock-trooper and a good cannon fodder. Air Elemental is the best unupgraded level 2 with a good growth. Ice Elemental is an average shooter. Fire elemental and It's upgrade sucks. The same with the earth one. Psychic and Magic elementals got no enemy retaliation and attacks all adjacent creatures. That's cool, but too broken with all the other good units. The Firebird is one of the best unupgraded tier 7 creatures, and Phoenix is the fastest.

In small maps it's better to start up with behemoth instead of Capitol and nothing to attack. You just rush... Fortress is very defensive and cheap - extremely good for beginning when you have lack of resources and lots of enemies. Conflux is deadly against slow creatures and Dungeon is deadly against mages(but only at very end) and almost such a good against might heroes - you just put on armageddon and then finish enemies up with your black dragons. ^^
